# Example of multiple key AES encryption for text files using the openssl v. 0.9.8+ command line utility
# Uses n public certs as key for MIME PKCS envelope, any individual private key can decrypt.
#
# If standard RSA ssh keys exist, these can be converted to public certs as well (and ssh keys can decrypt)
# 
# To sign (and verify) the encrypted file, one of the private keys is required, see:

Generating Authy passwords on other authenticators

---

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

---

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.

Principled Meta Programming for Scala

This note outlines a principled way to meta-programming in Scala. It tries to combine the best ideas from LMS and Scala macros in a minimalistic design.

• LMS: Types matter. Inputs, outputs and transformations should all be statically typed.

• Macros: Quotations are ultimately more easy to deal with than implicit-based type-lifting

• LMS: Some of the most interesting and powerful applications of meta-programming

BUT do note that this can be updated, so leave a link here so readers can see the updated information themselves.

1.13 and 1.14 are lumped together in this doc, you're on your own if you just want to go to 1.13 and not 1.14, for some reason.

1.15 stuff: https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e

Things in Advance

• ResourceLocation now throw on non-snake-case names instead of silently lowercasing for you, so you probably should go and change all those string constants now. More precisely, domains must only contain alphanumeric lowercase, underscore (_), dash (-), or dot (.). Paths have the same restrictions, but can also contain forward slashes (/).
